User activation link in admin email does not work

[jjnxpct]

Steps to reproduce the issue

Settings -> User registration: Enabled, Account activation by admin

Register as new user and use the link that is send to this user to first confirm the registration.

Admin then receives an email with a link to activate the user.
COM_USERS_EMAIL_ACTIVATE_WITH_ADMIN_ACTIVATION_BODY -> {ACTIVATE}

Log in to the frontend with the admin account (in our case not superuser)
Click on the link in the email. This will take you to the frontend.

Expected result

User should be activated and a notification message about that should show.

Actual result

The user is not activated and no message is shown. The user that is logged in to activate the net user is in stead redirected to the user profile view.

System information (as much as possible)

Joomla 5.2.3
PHP 8.3.14
10.6.20-MariaDB-cll-lve

Additional comments

This has worked before on the site we are experiencing issues now. So something must have changed?

I logged into the frontend as superuser. And I have the same problem.
